Parker,Independence, Mo. Application September 16, 1955, Serial No. 534,692 1Claim. (Cl. 183-51) The present invention relates to combined heatbafiies and filter attachments for baseboard and wall attached heatregisters, and more particularly for heat registers of the type usedwith forced air heating systems.

In forced air heating systems of the type employing registers along thebaseboard or in the wall of a room, the flow of air through the registerhas carried a sufficient amount of dirt, not eliminated by the furnacefilter, to smudge the wall surface above the register after prolongedperiods of heating. Eflorts have been made to produce furnace filterswhich will completely eliminate the problem. However, it has been foundthat such filters cannot be produced at a cost Which would make themeconomical to install. Hence, the smudging of the wall above theregister has been generally accepted as a necessary evil of the forcedair register heating system, therefore The primary object of theinvention is to provide a combined heat baffle and filter attachment forhot air registers which will simultaneously deflect the heated airoutwardly away from the wall lying just above the register, and filterthe layer of air lying closest to the bafiie.

Another object of the invention is to provide an air filtering baffle inwhich the filter is arranged in such a manner that it can be readilyremoved and replaced upon becoming saturated with dirt.

A further object of the invention is to provide a heat baflle structurefor attachment to an air register which will produce the desired effectof eliminating the smudging of the wall above the register and at thesame time present a neat appearance which will not be objectionable tothe eye of the user.

A still further object of the invention is to provide a combined heatbaflling and filtering attachment for hot air registers which will beinexpensive to manufacture, easy to maintain and simple to install.

Other objects and advantages will become apparent in the followingspecification when considered in the light of the attached drawings, inwhich:

Figure l is a perspective view of the invention, shown attached to aconventional air register structure;

Figure 2 is an enlarged vertical cross section taken along the line 22of Figure 1, looking in the direction of the arrows;

Figure 3 is a fragmentary front elevation of the attachment showing therelationship of the filter thereto, and

Figure 4 is a fragmentary detail view of the filter element, showing thestitching thereof.

Referring now to the drawings in detail wherein like reference numeralsindicate like parts throughout the several figures, the referencenumeral indicates generally a heat register of the type normallyassociated with a forced air heating system. The heat register 10 is ofa conventional nature and is shown merely to illustrate the manner inwhich the invention is attached thereto, and can have any conventionalform.

The heat register 10, as disclosed herein, rests on the floor 11 andagainst a wall 12. A baseboard 13 engages the sides 14 of the register10 to complete the finish of the room. The register 10 is provided withlouvers 15 on the forward face 16 thereof, which communicate with theinternal portions 17 of the register 10. Heat ducts (not shown) areconnected to communicate with the internal portions 17 of the register10.

An arcuate bafile 18 has a downwardly extending flange 19 projectingtherefrom with the flange 19 extending in front of the top face of theregister 10 and is secured thereto by means of fastening elements 20.The arcuate portion 18 has a generally semi-cylindrical cross sectionwith the concave portion 21 thereof facing outwardly toward the interiorof the room. The baflle 18 has one end edge 22 positioned adjacent theend 14 of the register 10, and the other end edge 23 positioned adjacentthe end Wall 13 of the register 10 so that the baflle 18 extendscompletely across the top of the register 10.

A filter 24 made of a wire screen tubing 25, formed around the filteringmaterial such as glass wool 26, is secured together by means of wirestitching 27 along one edge. The filter 24 extends throughout the lengthof the baffle 18 and is positioned adjacent the top outer edge 28thereof. Filter 24 underlies the outer edge 28 of the baffle 18 and issecured thereto by means of metal screws 29, or other suitable fasteningdevices.

In the use and operation of the invention, the baflie structure 18, withthe filter 24 attached thereto, is secured to the upper face of theregister 10 by means of the fastening elements 20. In this positionheated air flowing upwardly from the louvers 15 rises and, instead ofcontacting the wall 12, is deflected outwardly by the concave curve 21of the baflle 18. The layer of air closest to the baffle 18 is filteredthrough the filter 24, removing the dirt therefrom and producing acushion of clean air extending upwardly between the air not filteredthrough the filter 24 and the Wall 12. This, as it can be readily seen,will prevent the smudging of the wall 12 due to the unfiltered aircoming in contact therewith.

It will be understood that this bafl'le and filter will be made to fitany and all sizes of heaters, floor registers, where heat flows or isforced; floor furnaces, wall furnaces, or hot water heaters.

Having thus described the preferred embodiment of the invention, itshould be understood that numerous modifications and design changes toattach the device to all types and styles of heat registers and/orradiators may be resorted to without departing from the scope of theappended claim.

What is claimed is:

A combined air deflecting heat bafile and filter attachment for hot airregisters of the type including a generally rectangular body having therear thereof engaged against a building wall and the front thereofspaced outwardly therefrom comprising, an imperforate semi-cylindricalbody portion having a forwardly facing concave form, a flange integrallydepending from said semi-cylindrical body portion, means detachablysecuring said flange to the front upper edge of said register, a wirefabric tube, filter material in said tube, and means securing said tubehorizontally to the upper edge portion of the concave side of saidsemi-cylindrical body portion for filtering air.
